To @Z whom it may concern.-

Be it known that I, JACOB JACOBS, of New York city, in the county of New York and in the State of New York, have invented a certain new and useful Improvement in Bracing for Vault-Lights, Floors, Walls, &c.; and I do hereby declare that the following is a full, clear, and exact description thereof, reference beinghad to the accompanying drawings, in which- Figure l is a plan view of a vault-light embodying my construction. Fig. 2 is a plan view of the bracing of said light. Figs. 3 and i are side and end elevations of the said vaultlight, and Fig. 5 is a view showing the elements of which my bracing is constructed.

The object of my invention has been to provide a bracing for vault-lights, iioors, Snc., which shall be Vstrong and cheap and which shall be readily adapted to support lenses of varying sizes and to fit openings of different dimensions with a very small amount of cutting of the elements of my bracing.

In carrying my invention into practice, as illustrated in the drawings, I provide main braces A in the form of L-beams, which are in the instance chosen for illustration spaced apart the proper distance to receive the lenses B. The main braces A are connected by cross-braces O, which are preferably in the form of T-beams, whose iianges and webs are provided with J.shape slots c of a size adapted to receive the fiange and web of the main braces A. The cross-braces may be shifted along the main braces to form any convenient spacing and in the instance chosen for illus-A tration are spaced apart the length of the lens B. The lenses B may be of any desired construction and inthe instance chosen for illustration are provided with iianges that are adapted to rest upon the main braces A, and iianges b', that are adapted to rest upon the cross-braces C. The cross-braces may be riveted together, if desired, and either or both braces may be provided with holes t or c, respectively, through which may be threaded wires or rods for the better support of the cement for plaster to be held by the braces. The cross-braces may be placed below the main braces, as shown in the drawings, or the braces may be inverted, so that the crossbraces are on'top of the main braces. When the braces and lenses have been assembled,

the cement or other filling is lled in around the lenses to cover the bracing, preferably to the level of the upper surface of the lenses. Both the main and cross braces may be made in the form of I-beams or of beams of the cross-section of a -l-. The -lbraces may be made in the form of simple bars having no anges. The flanges of the main braces A are in the form of flat bars and provide flat supports for the fianges of the lenses. The flanges of the main braces A are therefore, in so far as supporting the lenses are concerned, fiat bars.

It is obvious that my bracing is capable of wide application. It can be used for sidewalks, to support the concrete between the main beams of a bridge, to support the floors, walls, partitions, and skylights of buildings. The bracing is also adapted for the ribs of ships. It will be seen that in the form above illustrated the portions of the cross-beams which have the 1 -slots removed therefrom are not materially weakened thereby, since the anges c2 are placed under compression between the webs a of the main braces. The portions of the webs c3 of the cross-braces which are subjected to a tensile strain are not injured by the slots.

It is obvious that various changes can be made in the above-illustrated construction which will be within the scope of my invention. Y

Having thus described my invention, what I claim is- 1. A vault-light, consisting of the combination of main braces having flanges,crossbraces having slots adapted to receive said flanges, said slots having contracted openings whereby both the upper and lower surfaces of said flanges are engaged in said slots, lenses having flanges adapted to rest upon said main braces, and concrete filling.

2. A vault-light consisting of the combina-l tion of main braces having fianges,crossbraces having slots adapted to receive said flanges, lenses having flanges in different planes adapted to rest both upon said main braces and upon said cross-braces, and a concrete filling.

3. A vault-light consisting of the combination of shaped bars, cross-bracesformed of T-shaped bars, said cross-braces having L- shaped slots formed in and beneath the flanges thereof, said slots being adapted to receive In testimony that I claim the foregoing I the flanges of said main braces, lenses having have hereunto set my hand. lower flanges adapted to rest upon the lianges l of the main braces, upper flanges adapted to JACOB JAQOBS 5 rest upon the flanges of the cross-braces, and Witnesses:
